J. WESLEY WEBBER, OF NEW YORK, N. Y.

DRILL.

SPECIFICATION forming part of Letters Patent No. 252,161, dated January 10, 1882.

Application filed January 3, 1876. Renewed October 25, 1880. Again renewed June 13, 1881. (Model.)

To all whom it may concern Be it known that I, J. WESLEY WEBBER,

of New York, N. Y., have invented an Improvemeut in Drills, of which the following is a specification.

The object of my invention is to so construct a machine that it will drill holes of various shapes and sizes and cut out pieces of various shapes and sizes, accomplishing the same by positive motion.

Figure 1 represents the working parts of my invention complete and together. 0 O is a slide working in a frame, N N. E is an oval plate fixed to the under side of theupper crosspicce of the slide 0. A is the driving shaft, passing downward through the cross-piece B ofthe trame N N and through theupper crosspiece of the slide 0 and plate E, extending through and projecting from the lower crosspiece of the slide 0. It is slotted at its lower end, as shown in Figs. 2 and 4. a a represent the pattern-plates, (see Figs. 5 and 6,) to be fastened under the plate E by the thumbscrews R B, (shown by dotted lines, Figs. 1 and 2,) which hold the pattern-plates in the position shown against a pin with a T-shaped head projecting through the holes P P. \Vhen held in this position the slot L forms a square or a circle, as the case may be. -K K represent cutters running through and working in the slotiu the lower end of shaft A,.both of which are pivoted on the pin D. S S indicate two slotted arms fixed to shaft A, through which the cutters K K work as their upper end travels in the slot L. J represents a half journal-box, attached by means of the screws shown, and removable so as to fit variousshaped cutters in the slotted shaft A.

Fig. 2 is a side View of my machine.

Fig. 3 represents cutters (in position for work) 40 Figs. 5 and 6 represent the pattern-plates with the slot L cut therein, in which the cutters K K work. (See Fig. 1.) Said patternplates are in two pieces or sections, and are'fitted around the shaft from opposite directions, and held by the T-shape headed pins and thumb-screws R, as shown in Fig. l. H H in dicate threaded holes, in which the thumbscrew It fits. (See Figs. 1 and 2.) P P show the holes through which the T-shape headed pins project from plate E, and assist to hold the pattern-plates, as shown in Fig. 1.

' By imparting a rotary motion to shaft A the upper end of the cutters K K are carried by positive motion in the slot I1. A similar motion is imparted to the lower end of the cutters, which cut the desircdshaped hole or piece.

I claim as my invent-ion- The combination, with the drill-shaft and the pattern-cam, of the cutters and cutter-levers, connected to one another and to the drill-shaft by a single pivot, and the slotted arms S, substantially as described.

J. WESLEY WEBBER.
